Hi everyone
I'd not heard of John Giddings remanufactured vertical links. Does anyone know how/when/ how many/£how much? Was this though the SP250 Owners' Club website, or did I miss it here? How strong are they compared to the original? They can shear off at the top of the threaded portion. When Barry frirst proposed having them remanufactured many decades ago there was not enough interest. Substitution with the complete TR6 front suspension requires a new stub axle to replace the TR item, which was available from New Zealand some years ago. I know not if that is still the case. However I believe that the TR system removes the altered steering geometry that is a feature of rack + pinion converted cars (on full lock).
Thanks
Regards
Geoff

Re: SP 250 vertical links
Geoff,
Yes it was a post here that alerted me to them. John has three Darts and was having a batch made for principlally himself and sold them to others at £1200 a pair. However, as you would expect, no warranties of any kind. Before letting others have any John fitted them to his cars and ran them for some months.

Re: SP 250 vertical links
I stand to be corrected but weren't the vertical links drop forged, casting in those days left weaknesses which drop forging over came, I discussed the refurbishment many years ago with some very highly skilled specialised welders, their opinion was to cut off the thread machine a recess, shrink fit a new thread and weld in place. With todays CNC machines it may be cheaper to machine the unit from a solid billet rather than a specialised casting that overcomes the weaknesses of yesteryear.
Owner since the 70's, Genghis is slightly to my left.
Re: SP 250 vertical links
For all you metallurgists out there, is the strength of a drop forged item likely to alter over time? And how old before the risk of breakage becomes a concern? Or is that not an issue? We're not talking about extraordinary alloys made for highly stressed WWII era piston engines after all, although one hears it said that Daimler materials were sometimes of unusually high quality, or does that just apply to the engines?

Is this something a 3D printer could handle? Not sure what materials are used in the process or if the finished product would be strong enough. Others more knowledgable than me might have the answer.

Sorry, thanks for putting me right, I missed it. £1200 represents good value relative to what Barry quoted long ago, which I think was around £1500/pr. What would that be now ~£5k perhaps?
I think I'll pass for now however, as I do have a little used pair tucked away, somewhere!.

Re: SP 250 vertical links
Hello,
Not being a SP250 owner, I'd like to check something if I may.
In the thread, reference is made occasionally to greasing the trunnions - I was always under the impression that trunnions should be oiled with something along the lines of EP90 oil and not grease.
The reason I raise this is that all Triumphs fitted with trunnions are specifically directed to use oil and not grease. The reason for this is that the oil moves with the trunnion providing constant lubrication, whereas grease is fixed and does move with trunnion travel.
It may be the case that the set-up on the SP250 is different, hence my my enquiry through curiosity.
Many thanks.
Richard.
